You do not need any tools to run this.  Just copy the code that is posted in the article, open notepad and paste the code in a new text document.  Save the file with a ".vbs" extension and double click on the file to run it.  Depending on the Windows Version you are running, you may have a dialog box prompt you that running scripts may not be safe do you wish to run the script or block it.  From the dialog box select to trust or allow the script to run.

Requirements

1. Windows OS (Windows 98 may be OK, but I know Windows 2000 + will work.)
2. Windows Scripting Host (You may already have it installed.  If not do a search on Microsoft's Web Site.)

Hope this helps.
